Title: Improved process for delustring and rendering textile fabrics crease-resisting
IPC: D06M15/423
Filed: 1937-07-16
Abstract: Textile materials are impregnated with urea or the like and formaldehyde, or with a soluble partial condensate thereof, and an acid or potentially-acid substance, part of the resin components converted to a non-resinous condensation product and the remainder converted into resin by subsequent drying and heating, whereby the material is delustred in addition to the effect produced by the resin.  The heating may be effected in the presence of additional formaldehyde or urea to produce an anticrease effect.  In examples: (1) a textile material is impregnated with water solution of a urea formaldehyde pre-condensate, squeezed, the damp material immersed in dilute hydrochloric acid until delustred, washed, dried, impregnated with formaldehyde containing tartaric acid, squeezed, dried and heated for 2 mins. at 170 DEG  C.; (2) material is impregnated with a solution of a urea-formaldehyde precondensate containing tartaric acid, allowed to stand without drying until precipitation of methylene urea takes place, dried and heated for 2 mins. at 170 DEG C.  The treated material may be subjected to a swelling treatment as described in Specifications 437,361 and 437,441. Specifications 291,473 and 449,243 also are referred to.

Title: Automatic firearm having a device for regulating the firing rate thereof
IPC: F41A19/03
Filed: 1971-06-10
Abstract: 1340922 Hydraulic buffers MAUSERWERKE AG 10 June 1971 [1 July 1970] 19951/71 Heading F2S [Also in Division F3] The firing rate of an automatic firearm is regulated by a buffer assembly which is mounted coaxially and comprises mechanical and hydraulic members which are automatically coupled with and uncoupled from a breech of the firearm. The buffer assembly absorbs kinetic energy from the breech and returns the latter to its firing position. The hydraulic members are arranged concentrically in the mechanical members and effect the regulating of the firing rate. In an embodiment a barrel 1 has a screwthreaded aperture which receives one end of a buffer casing la therein and has a stepped aperture which receives a buffer head 2 therein. A spring 3 is positioned in the casing la and urges the head 2 against the step in the aperture of the barrel 1. A slider head 6 is slidably mounted in the head 2 and is fixed to a cylinder 5 which is slidable on a piston 4 supported by a piston-rod 4d secured to a closed end 1b of the casing la. A recoil spring 8 disposed within the buffer spring 3 bears against the end face of the head 6. A breech 12 has a fastening pin 13, attached thereto, the latter having a head 13c with tapered surfaces 13a, 13b. In use firing of the firearm causes the breech 12 to move towards the buffer assembly and the head 13c of the fastening pin 13 to enter a recess 6b of the head 6 and strike an end face 6a thereof thus causing the head 6 to move against the spring 8. The breech 12 strikes the buffer head 2 and compresses the spring 3 which absorbs the kinetic energy of the breech. The head 13c of the pin 13 is fastened in the recess 6b of the head 6 by members 7 as shown in Fig. 2. Pressure-fluid flows from a chamber 5a in the cylinder 5 to a chamber 5b, via bores 4a in the piston 4, sealing members 11a being lifted by the passage of the fluid. The time expended in this operation is proportional to the complete absorption of the kinetic energy of the breech 12. The energy stored in the springs 3, 8 tends to return the breech to the firing position but is controlled by the pressure-fluid which passes from the chamber 5b to the chamber 5a, via radial bores 4b and an axial bore 4c formed in the piston-rod 4d. The flow is regulated by a needle 9 having a cone-shaped end 9c and which is screwably adjustable in a bore 9b formed in the piston 4. When the buffer assembly has moved to the position shown in Fig. 1 the members 7 have moved radially outwardly to release the pin 13 from the recess 6b of the head 6.

Abstract: 243,080. Hall Telephone Accessories. Ltd., (Hall, F. W.). Aug. 23, 1924. Telephone apparatus; coin action, thrust and weight.-In a coin-collecting device for tedephone services in which the inserted coin or coins are held in a position of suspense, the coins are projected into a money-box or " cashed in " by an automatic coin projector restrained bv an automatic locking-device, which is released electrically, if the desired connection is obtained, but is manually operated to return the coins if the connection is not obtained. The coins, according to their denomination, are inserted in separate shoots provided with testing and signalling devices, and pass to a carrier secured to a quadrant Q which is pivoted at Q<1> and is provided with a weighted arm Q<3> tending to move it to deliver the coins to a money-box- As a coin is inserted it acts on a pin l<1> to move a lever m which abuts against a pin s on a lever t. The movement of the lever t closes contacts 8, 9 to short-circuit temporarily the calling transmitter and through a link u moves the quadrant Q from its " cashing in " position to the position shown, where it is held by the armature L of a polarized relay 0 engaging a pin L'. The coins rest on and depress a balance arm r which closes contacts 1, 2 for calling the exchange or rendering operable a calling apparatus, such as an impulse dial. If the required connection is obtained, the circuit of a reversing relay controlled by the supervisory relay on the called side is closed and causes the relay 0 to disengage the lever L from the quadrant. If the call is ineffective, the subscriber presses a button B which, acting through a lever y, swings the quadrant to the right to project the coins into a return shoot w<1>. The button B opens contacts 10, 11 and closes contacts 12, 13 which earth the. coil of a holding relay, thereby keeping the circuit disconnected until the operator has cleared the line. The signalling devices at the ends of the coin shoots, which are used for longdistance tolls, are a bell o, gong n and a yoke attached to the bell. A small auxiliary transmitter fixed inside the bell transmits the signals to the exchange. Fraud, preventing.-If a knife or other implement is inserted through the coin shaft for fraudulent purposes, the contacts 8, 9 are closed and short-circuit the transmitter.
